'BEAT R ENGINE.

Application filed May 17,1923. Serial No. 639,528.

To all whom it may COW-067%.

Be it known that 1, DAVID C. DAVIS, a citizen of the United States, residing at Otsego, county of Allegan, State of Michigan, have invented certain new and useful Improvements in Beater Engines, of which the following is a specification.

This invention relates to improvements in beater engines.

The main object of the invention is to provide an improved beater engine in which the beater roll is supported so that it may be accurately adjusted relative to the bed plate and at the same time in such a manner that the parts are not likely to be injured by the passing of an obstruction through the engine.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this application, in which:

Fig. I is a plan view of a beater engine embodying the features of my invention, the

tub and the beater roll being shown conventionally.

Fig. II is a side elevation of one of the lighterbars and its support, the parts being partially in section on a line corresponding to line 22 of Fig. III.

Fig. III is a fragmentary view looking from the right of Fig. II.

In the drawing similar reference character refer to similar parts throughout the several views.

Referring to the drawing, 1 represents the tub, 2 the beater roll and 3 the beater roll shaft. The structural features of these parts form no part of this invention and are, therefore, not detailed herein.

The beater roll is carried by the lighter bars 4 having bearings 5 in the shaft 3. The lighter bars are supported in the posts or pedestals 6 which are vertically slotted at 7 to receive the ends of the lighter bars, the lighter bars having holes 8 therein to receive the hanger rods 9. These hanger rods are adjust-ably supported by the nuts 10 in the form of gears or nuts adapted to receive the wrench, as 11. The supporting springs 12 are arranged on the hangers 9 below the lighter bars so as to carry the load. Supporting nuts 13-for these springs are threaded upon the lower .ends of the hangers.

To simultaneously adjust the corresponding ends of the lighter bars I provide a shaft 14 having worms 15 thereon coacting with the nuts 10. v

l/Vith this arrangement of parts the beater roll are supported so that parts of the en gine are not likely to be broken when the beater roll falls after passing over an obstruction, as frequently results in beater engines now in common use. At the same time the beater roll is supported so as to facilitate accurate adjustment thereof relative to the bed plate.

Having thus described my invention, what I claim is new and desire to secure by Letters Patent, is:

1. In a beater engine, the combination of beater roll lighter bars, posts vertically slotted to receive the ends of said bars, hangers for said lighter bars suspended with said posts and arranged through said bars, the bars being vertically movable on, the hangers, lighter bar supporting springs arranged on said hangers below the bars, said hangers having spring supporting nuts threaded thereon, adjusting gears for said hangers threaded upon the upper ends-thereof, and an adjusting shaft provided with worms meshing with said gearswhereby corresponding ends of the lighter bars are simultaneously adjusted.

2. In a heater engine, the combination of beater roll lighter bars, post vertically slotted to receive the ends of said bars, hangers for said lighter bars suspended with said posts and arranged through said bars, the bars being vertically movable on the hangers, lighter bar supporting springs arranged on said hangers below the bars, said hangers having springsupporting nuts threaded thereon, and adjusting nuts for said hangers threaded upon the upper ends thereof.

3. In a heater engine, the combination of beater roll lighter bars, posts vertically slotted to receive the ends of said bars, hangers for said lighter bars suspended with said posts and arranged through said bars, the bars being vertically movable on the hangers, lighter bar supporting springs arranged on said hangers below the bars, said hangers having spring supporting nuts threaded thereon, and adjusting means for 5 said hangers.

4. In a beater engine, the combination of beater roll lighter bars, posts, hangers for said lighter bars arranged through said bars, lighter bar supporting springs arranged on 10 said hangers below the bars, adjusting gears for saidihangers threaded upon the upper ends thereof, and an adjusting shaft provided with worms meshing with said gears whereby corresponding ends of the lighter bars are simultaneously adjusted.

5; In a beater engine, the combination of beater r011 lighter bars, posts, hangers for said lighter bars arranged through said bars, lighter 'bar supporting springs ar ranged on said hanger below the bars, and adjusting nuts for said hangers threaded upon the upper ends thereof.

In witness whereof I have hereunto set my hand and seal.
